A six-point mounted front subframe

Abstract

The invention belongs to the technical field of vehicle accessories, and specifically is a six-point mounted front subframe, comprising a first beam, a left longitudinal beam, a second beam, a mounting seat and a right longitudinal beam, wherein the bottom of the first beam is fixedly connected to the left longitudinal beam and the right longitudinal beam by bolts, and the bottoms of the left longitudinal beam and the right longitudinal beam are fitted with the second beam. The six-point mounted front subframe, through the combined use of accessories, compared with the traditional four-point mounting, is changed to a six-point mounting, and has a larger range for reducing the weight of chassis parts while meeting performance requirements, thereby meeting collision requirements, ensuring automobile safety, and effectively improving assembly requirements. In addition, transverse spring columns are arranged inside the left longitudinal beam and the right longitudinal beam to increase transverse buffering performance and reduce deformation probability, so that the main curved frame and the secondary curved frame at the bottom of the second beam support the bottoms of the left longitudinal beam and the right longitudinal beam, thereby improving load buffering capacity, reducing vibration intensity, and improving driving stability.

Description

Technical Field

[0001] The invention relates to the technical field of vehicle accessories, in particular to a six-point mounted front auxiliary frame. Background Art

[0002] A car is a power-driven, non-track-borne vehicle with four or more wheels, mainly used for: carrying people and goods; towing vehicles carrying people and goods; and for special purposes.

[0003] The automobile subframe is one of the accessories of the automobile. The subframe can be regarded as the skeleton of the front and rear axles and is a component of the front and rear axles. The subframe is not a complete frame, but a bracket that supports the front and rear axles and suspension, so that the axles and suspension are connected to the "main frame" through it. It is usually called "subframe". The function of the subframe is to block vibration and noise and reduce its direct entry into the car compartment, so it mostly appears in luxury cars and off-road vehicles. Some cars also install subframes for the engine. The traditional load-bearing body without subframe has its suspension directly connected to the body steel plate, so the suspension rocker arm mechanism of the front and rear axles are all loose parts, not assemblies.

[0004] At present, chassis parts in the automobile industry need to meet collision requirements. For this reason, there are only four-point installed automobile chassis parts, and some of them cannot meet the shrinkage requirements. At the same time, the subframes with four-point installation need to improve product quality to meet the target requirements, which is not conducive to cost control and cannot reduce weight. In addition, the longitudinal beam is a hollow structure, lacks lateral impact resistance and is very easy to deform. When the longitudinal beam and the cross beam are fastened with bolts, it is not easy to alleviate the vibration and the driving stability cannot be improved. Summary of the invention

[0005] The purpose of the present invention is to provide a six-point mounted front subframe to solve the problem raised in the above background technology that the current chassis parts in the automobile industry need to meet the collision requirements, and for this reason, there are only four-point mounted automobile chassis parts, some of which cannot meet the collapse requirements. At the same time, the subframe with four-point installation needs to improve product quality to meet the target requirements, which is not conducive to cost control and cannot reduce weight. In addition, when the longitudinal beam is a hollow structure, it lacks lateral impact resistance and is very easy to deform. When the longitudinal beam and the cross beam are fastened and connected by bolts, it is not easy to alleviate the vibration and the driving stability cannot be improved.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a six-point mounted front subframe, comprising a first beam, a left longitudinal beam, a second beam, a mounting seat and a right longitudinal beam, wherein the bottom of the first beam is fixedly connected to the left longitudinal beam and the right longitudinal beam by bolts, the bottoms of the left longitudinal beam and the right longitudinal beam are fitted with the second beam, the top of the second beam is fixedly connected to the mounting seat by screws, the top of the first beam is provided with a first mounting hole and a second mounting hole, the top of the left longitudinal beam is provided with a third mounting hole and a fourth mounting hole, and the left side wall of the inner cavity of the left longitudinal beam is fixedly connected to the left longitudinal beam by screws. A left pad is fixedly connected with a bolt, a transverse spring column is welded to the right side wall of the left pad, a right pad is welded to the right side wall of the transverse spring column, the right side wall of the right pad is fixedly connected to the right side wall of the inner cavity of the left longitudinal beam by bolts, the bottom of the second beam frame is integrally connected with a main curved frame and an auxiliary curved frame, the bottom of the main curved frame is fixedly connected with a mounting seat by bolts, the top of the mounting seat is fixedly connected with a vertical spring column by a pin shaft, the top of the vertical spring column is welded to the top of the inner cavity of the left longitudinal beam, and a fifth mounting hole and a sixth mounting hole are opened on the top of the right longitudinal beam.

[0007] Preferably, the diameters of the first mounting hole, the second mounting hole, the third mounting hole, the fourth mounting hole, the fifth mounting hole and the sixth mounting hole are the same.

[0008] Preferably, the internal structure of the right longitudinal beam is the same as the internal structure of the left longitudinal beam.

[0009] Preferably, the inner cavity width of the main curved frame is greater than the width of the left longitudinal beam, and the inner cavity width of the auxiliary curved frame is greater than the width of the right longitudinal beam.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the six-point mounted front subframe, through the combined use of accessories, compared with the traditional four-point mounting, by changing to a six-point mounting, has a larger range for reducing the weight of chassis parts while meeting performance requirements, meets collision requirements, ensures automobile safety, and effectively improves assembly requirements, and a transverse spring column is arranged inside the left longitudinal beam and the right longitudinal beam to increase the transverse buffering performance and reduce the deformation probability, so that the main curved frame and the auxiliary curved frame at the bottom of the second beam frame support the bottom of the left longitudinal beam and the right longitudinal beam, thereby improving the load buffering capacity, reducing the vibration intensity, and improving the driving stability.
